I am not able to get any visualisation of the cube in rviz as well when using this topic /basic_grasping_perception/object_cloud in rviz
Have you sent the goal to the /find_objects Action Server? Keep in mind that you need to send a goal to the Action Server in order to trigger the perception process. I’ve just tested it in the Academy and it is working properly for me.
Yes sir , I gave the goal command. I will try again and report back sir.
How I could send the goal to action Server?
You have it explained in the Chapter’s notebook. It’s something like this:
rostopic pub /basic_grasping_perception/find_objects/goal grasping_msgs/FindGraspableObjectsActionGoal "header: seq: 0 stamp: secs: 0 nsecs: 0 frame_id: 'base_link' goal_id: stamp: secs: 0 nsecs: 0 id: '' goal: plan_grasps: false"
